SASH- LOCK.

SPECIFICATION forming part of Letters Patent No. 675,263, dated May A28, 1901.

Application tiled January 28, 1901I Serial No. 45,113. (No model.)

To @ZZ whom it may concern:

Be it known that I, DANIEL T. BROWN, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Sash-Locks and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to sash-locks.

The object of the invention is to provide alock of this character by means of which the sashes-the upper and lower ones-may be simultaneously locked the one to the other and tothe window-frame, so that a person may adjust the upper or lower sash, or both, to ventilate or air the room and at the same time lock them to prevent the entrance of an unauthorized person.

With this and other objects in View the invention consists of certain novel features of construction, combination, and arrangement of parts, which will be herein after more fully described, and particularly pointed out in the appended claim.

In the accompanying drawings, Figurel is a perspective view ofwa portion of a window-frame, showing the sashesin locked and closed position. Fig'. 2 is a similar view showing the lower sash elevated and loclged in position. Fig. 3 is a similar view showing the lower sash elevated and the upper sash lowered and locked in their adj usted positions. Fig. 4is a longitudinal sectional view through the bolt and casing. Fig. 5 is a detail perspective view of the bolt removed from its casing.

Referringnow more particularly to the drawings, the numeral 1 denotes the window frame, and 2 and 3 the upper andlower sashes, respectively. Th'e sash 2 is provided with a vertical row of bolt-seats 4, which seats are preferably in the form of notches cut into a bar 5, which is bolted or otherwise secured to the inner face of the side piece of the sash. The inner facev of one of the side pieces of the window-frame is provided with a vertical row of bolt-seats 7. The meeting or upper rail of the lower sash is provided with a fastener of any desired construction, which is designed to simultaneously lock the sashes one to the other and lock them to the windowframe. This fastener preferably consists of a casing 8, screwed or otherwise secured to the upper surface of the meeting-rail,in which is arranged a springactuated bolt-shank 9, having bolt-heads 10 and 11, respectively, ar` ranged at right angles and designed toengage the seats 4 and 7. The shank is provided in its upper surface with two notches 12 and 13, which are adapted to be engaged by a latch 14, pivoted to the casing. This latch will serve to hold the bolt-heads out of engagement with their respective seats when itis not desired to lock the sashes and to hold the bolt-heads into engagement with the seats when the sashes are locked.

If it be desired to lower the upper sash, this may be done and the room be ventilated from the top. If it be desired to ventilate from below, the lower sash is elevated and is held in locked position. If it be desired to adjust both sashes-that is, lower the upper and raise the lower-this also may be done and the sashes be locked one to the other and to the window-frame. It is oftentimes desirable to adjust the sashes in their normal position-say at a distance of two or three inches-especially in the summer, to allow tne room to ventilate; but this is made undesirable from fear of the entrance of some unauthorized person, either while the occupant of the house is asleep or temporarily out. The employment of a lock of this character removes all grounds forfear, as the sash may be securely locked against the en trance of an unauthorized person, while at the same time one or both may be adjusted for the purpose of ventilation, or they both may be closed.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and advantages of myinvention will be readily understood without requiring amore extended explanation.

Various changes in the form, proportion, and minor details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

IOO

Having thus described xny invention, what I claim, and desire to secure by LettersPatent, is-

The combination of a window-frame having a vertical row of bolt-seats, upper and lower sashes, the former of which is provided with a vertical row of bolt-seats, and a fastener for sim nltaneously engaging said seats for locking the sashes one to the other and to the window-frame, said fastener comprising a shank having bolt-heads which are arranged at right angles to each other, said shank bcing provided with notches and a latch to engage said notches to hold the bolt-heads in locked or unlocked position and the spring for forcing the bolt-heads into locked position, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

DANIEL T. BROWN.
